Overview
Cloud-native networking moves away from traditional hardware-based networking toward software-defined, identity-based models. It focuses on providing connectivity, security, and observability for containers and microservices.
Key Concepts
- Flat Network: Every pod in a cluster can communicate with every other pod without NAT.
- Service Discovery: Automatically finding the IP addresses of services as they scale.
- Network Policy: Defining fine-grained security rules for pod-to-pod communication.
- Service Mesh: Managing complex traffic patterns and security between services.
Importance
Essential for enabling the scalability and agility of modern cloud applications.
